[Elecraft] Radio and amplifier environmental specifications

[Gary Johnson]

I've never seen an operating temperature spec for any ham equipment. When we built our remote station (K3/KPA1500 in an insulated 20 ft shipping container), my main concern was not so much temperature as condensation. Moisture is a slow-motion disaster for unsealed, uncoated circuit boards. Ventilation can help, but there are times when everything is going to be soaking wet. And then there’s dust. So we added a Mitsubishi 1-ton mini-split heat pump with the sepoints pretty wide (55 and 80 F). It doesn't run much but the equipment is dry and clean. Themostat is a Nest, controlled from an app.
